A postage stamp is proof of pre-paying a fee for postal services. Usually a small paper rectangle which is attached to an envelope, signifying that the person sending the letter or package has paid for delivery, it is the most popular alternative to using a prepaid-postage envelope.
Stamps have been issued in other shapes, however: the circular stamps of New Zealand, triangular and pentagonal, and Sierra Leone and Tonga have issued self-adhesive stamp in the shape of fruit, Bhutan has issued a stamp with its national anthem on a playable record, etc. Stamps have also been made of materials other than paper, usually embossed foil; Switzerland made a stamp partly out of lace and one out of wood, the United States produced one made of plastic, and the German Democratic Republic once issued a stamp made entirely of synthetic chemicals.
